Title: Semiconductor photodiode
Inventor: OTA ATSUSHI
IPC: H01L31/10
Filed: 1987-02-18
Abstract: PURPOSE:To obtain a photodiode of single element with excellent selectivity of wavelength, by forming a grating in a light receiving part, and selectively guiding the only light of Bragg wavelength defined by a grating pitch to a depletion layer. CONSTITUTION:Among lights making vertical incidence to a grating part 8, the only light of Bragg wavelength lambdaB defined by a grating pitch is selectively guided to a high resistance layer 4, and guided till the lower part of an electrode 1. By applying an inverse bias voltage between a P-side electrode 1 and an N-side electrode 2, the vicinity of the lower part of the electrode 1 operates as a PIN photodiode, and a photocurrent flows. Thereby an incident light quantity can be monitored. As the only light having a wavelength corresponding to the Bragg wavelength is guided, the photodiode responses to a light in a very narrow range of wavelength. The photodiode with excellent wavelength selectivity for receiving light can be obtained.

Abstract: PURPOSE:To obtain a rotary anode X-ray tube with reduced rotary vibrations and capable of rotating stably for a long time by coating the surface of the bearing support member of a motor rotor with a black or black gray solid lubricating agent. CONSTITUTION:By coating the surface of a bearing support member 6 with a black gray solid lubricating agent, the radiation ratio is made 0.6-0.8 which is two to three times as large as the conventional one, and the heat quantity reaching a low temperature bearing support member 6 from a high temperature motor rotor 3 and a shaft 4 is increased, thereby the temperature difference between the inner and outer wheels 5b, 5c is decreased by about 30 deg.. By decreasing the temperature difference by 30 deg., the radial gap between ball bearings 5d, 5e can be reduced by 8mum, thus unstable rotary vibrations of an anode target 1 can be mitigated at a room temperature and an unstable condition during an initial rotation period and further even when the anode target 1 is cool.
